DUMjP lNG-CAR.

SPECIFICATION forming part of Letters latent No. 463,869, dated November24, 1891.

Application filed May 29, 1891.

To all whom it may concern.-

Be it known that I, CALEB D. PAGE, a citizen of the United States,residing at Tacoma, in the county of Pierce and State of WVashington,have invented certain new and useful Improvements in Dumping-Oars, ofwhich the following is a specification.

This invention relates to dumping-cars provided with pivoted boxes; andit consists in the construction and novel arrangement of parts wherebythe two boxes are locked in place, unlocked, and caused to dischargetheir contents simultaneously by manipulating one of the boxes only.

My invention has further relation to a mechanism for locking the twosections in place when they are being loaded and for readily unlockingthem when it is desired that they shall discharge their contents.

My invention has still further relation to the provision ofremovably-pivoted side pieces and means for holding them in place.

The object of my invention is to provide a dumping-car which shall besimple in con struction, easy to operate, and which may be readilyloaded from the sides instead of from the top when the exigencies of thecase shall so require.

I have illustrated my invention inthe accompanying drawings, in which-Figure 1 is an end view, partly in section, showing the boxes locked inan upright position. Fig. 2 is a similar view showing the boxes freedfrom the locking mechanism and tilted to discharge their contents; andFig. 3 is a top plan view of the boxes and car-body, showing thedraw-head and side-sill extensions at one end of the car only.

Similar letters of reference indicate similar parts throughout thedrawings.

A designates the, truck of the car, constructed in the well-knownmanner, upon which is mounted the casing E, constituting the outer partof the car proper, and which surrounds the boxes B B. These boxes arepivotally connected at their bottoms to the truck A through the mediumof the hingejoints P P, which are preferably located to one side of thecenter of gravity in order to cause the preponderance of weight of theSerial No. 394,549. (No model.)

loaded car to be toward the outer side of the car, so that when theboxes are released from the locking mechanism hereinafter described theywill automatically tilt and discharge their contents, as shown in Fig.2. The boxes 13 B are inclosed on three sides only, the outer sidesbeing open, and the sides G G of the casing serve as a fourth side toeach, respectively, when the boxes are in the upright position shown inFig. 1.

I will now describe the locking mechanism by which the boxes are held inposition for loading. Extending from end to end of the car and situatedin the space between the two back sides of the boxes is a rod 0, whichworks in journals d 61, attached to the ends E E of the casing. This rodmay be of iron or steel. Attached to the ends of the rod 0 are catches cc, to which are secured leverhandles 6 e, which normally rest on the topedges of the box, which they look, and extend at a right angle to therod 0. The rod 0 is situated a little below the level of the tops of theboxes B B. The catches a c are bent downward to form an angle with theleverhandle and curved outward to encircle the journal-bearings d d, andat the point where they form angles with the lever-handles they areprovided with detents t', which normally engage stops k, attached to theupper inner corners of one of the boxes. The surface of the detents isso inclined that the catches may be readily disengaged from the stopslcwhen the lever-h andles are lifted. The rod, catches, andlever-handles above described form what I have termedin the claims alocking-lever.

In practice I may make the rod 0, catches a c, and lever-handles e e ofone piece of iron or steel, or I may make either or all of these partsseparate and unite them rigidly together without departing from thespirit of my invention. 7

To secure the simultaneous action of the two boxes, I connect themtogether by a toggle-joint, which is formed by stay-rods as 00,journaled at their upper ends to hangers q q, attached to the lowerinner corners of the boxes and united at their lower ends by ajournal-bolt a. By the provision of this con nection between the twoboxes it will be seen that it is only necessary in looking, unlocking,or tilting the boxes to manipulate the locking-lever, when both boxeswill be simultan eously and in a like manner operated upon.

I prefer for the present to use but one toggle-joint connection attachedcentrally underneath the backs of the boxes; but I may decide to use twoor more such joints, and I may attach them to the sides or backs of theboxes, the exact point of attachment being immaterial; or for greatersimplicity of construction I may decide to attach one stay-rod of thepair rigidly to one of the boxes, and in so doing in no wise depart frommy idea of securing the simultaneous action of the boxes.

To facilitate dumping in case the boxes should not be properly loaded, Iemploy the lever F, Fig. which is inserted in keepers (not shown)attached to the end of one of the boxes near itsinner side, where it canthus be easily operated to tilt the boxes by the same person who unlocksthem. I prefer to make this lever of metal with a broad thin bladesquare at the end suitable for use in loosening such of their contentsas may adhere to the sides of the boxes. The boxes being open on theirouter sides are closed when in an upright position by the sides G G ofthe casing E. These sides conform in shape to the configuration of theends of the boxes, and in the present case are of the angular shapeshown. They have attached to their upper edges journals f f, by whichthey are supported in bearings g g, attached to the ends of the car. Thejournals ff are bent at their outer ends, as shown in Fig. 3, to preventthem from slipping out of place if, from undue strain or other cause,the ends of the car should bulge out. As a further means for securingthese journals in place, I provide the turn-buttons h h, which serve askeepers to prevent the journals being lifted from their bearings. Tosecure the bottom of the side in place when the boxes are being loaded,I attach to the bottom of each box, so as to project slightly beyond it,angular keepers o o, the toes of which project upward and prevent thesides from swinging outward.

The operation is as follows: The parts being in the position shown inFig. 1, the operator, standing at one end of the car, lifts thelocking-lever, which releases the detents i from contact with the stops7;. The lever-handle is then dropped and rests on the stops 7a, whichslides along the under surface of both handles as the boxes tilt on thehinge-joints I P. Should the load not be properly placed in the boxes,so that they over-balance readily, they may be tilted by the lever F.The sides G G, so soon as the boxes have tilted far enough to releasethem from engagement with the keepers 0 0', swing outward and allow thecontents of the boxes to discharge readily. hen the boxes are returnedto their upright position, the stops 7; slide along the under sides ofthe'leVer-handles until the detent is reached, when the 1ever-hand1esautomatically drop and the boxes are locked in place.

It may be desired to fill the boxes from the sides, as by shoveling,rolling on stones, stumps, or the like, and when this is the case it isnecessary to remove the sides. This can be easily done by turning theturn-buttons h h to one side, when the sides can be lifted out of theirbearings and taken off.

Although I have described my invention as particularly applicable tograding-cars, I wish itundersto'od thatI do not limit myself to suchapplication, as my invention may with slight modification as to themodeof attach ment to the trucks be applied withequally satisfactoryresults to standard-gage car,ballast'car, coal-car, or ordinarywagon-trucks.

WVhat I claim as new, and desire to secure by Letters Patient, is
